The Harry Potter books get digital illustrations that mimic the magic images in the Harry Potter books.
...It still falls short of the wizard world versions, but maybe that's in part because we know how the trick works these days; maybe wizards aren't as wowed by their own living pictures either.
Available exclusively through Apple books (or iTunes or whatever they're calling it these days), at least for now. Standard digital versions that work on all platforms available at Pottermore.com.
Surprisingly, the new versions are competitively priced with the existing editions at $9.99 each; so if you read on an Apple device, and you like to watch the occasional looped cartoon out of the corner of your eye as you read, then why not.
